废话不多说，直接上代码
package com.car;
interface Carr{
//汽车名称
String getName();
//获得汽车售价
int getPrice();
}
class BMW implements Carr{
public String getName(){
return "BMW";
}
public int getPrice(){
return 300000;
}
}
class CheryQQ implements Carr{
public String getName(){
return "CheryQQ";
}
public int getPrice(){
return 20000;
}
}
public class Car {
private int money=0;
public void sellCar(Carr car){
System.out.println("车型："+car.getName()+"单价："+car.getPrice());
money+=car.getPrice();
}
public int getMoney(){
return money;
}
public static void main(String[] args) {
Car aShop = new Car();
aShop.sellCar(new BMW());
aShop.sellCar(new CheryQQ());
System.out.println("总收入："+aShop.getMoney());
}
}
